Grand Sable Dunes temporary closure to all public entry for visitor safety
Grand Sable Dunes are rapidly eroding into Sable Creek and Lake Superior. The area from the trail to the Grand Sable Dunes north to the beach along Lake Superior to the west side of Sable Creek is temporarily closed. Follow closure signs for your safety.
About 60 species of native and non-native fish are present in the lakes and streams of Pictured Rocks National Lakeshore and the nearshore waters of Lake Superior. The park's many beautiful fishing locations attract anglers of all kinds.
From 1997 to 2005 coaster brook trout, a brook trout that spends much of its life cycle in Lake Superior, was experimentally re-introduced in the Mosquito River, Sevenmile Creek, and Hurricane River, in concert with a Lake Superior-wide restoration program. From 2008 to 2011, non-native steelhead trout and coho salmon were removed from Sevenmile Creek as part of a study to determine how their absence would affect native brook trout population levels, as well as their movement patterns and behavior.
The lakeshore has also been involved in a NPS Great Lakes Network research project to detect toxic chemicals and other contaminants in fish. Since 2008, northern pike and yellow perch (along with other species) from the park's four largest lakes have been tested for a variety of toxins including mercury, lead, DDT, and PCBs. Along with the park's extensive water quality testing, the data from this project will help park scientists better understand the interactions between toxins and wildlife health.

Did You Know?
Several species of plants in the Buttercup Family are aquatic, growing underwater in lakes and ponds. A few are even amphibious, meaning that a single plant lives partly on sand along a shoreline and partly submerged. Such plants have runners, like a strawberry plant, and grow roots along the runners. The submerged leaves appear quite different from the ones growing in air.
